After application of the final layer, allow the release agent to cure for at least 30 min at room temperature. In case of using new, repaired or porous moulds, apply a further 2 coats to ensure best release performance. In order to avoid hazing and poor durability of the release film, we recommend to test the gun settings as well as the spray technique on the mould edge first
and to immediately remove over application or drippings by means of wiping or rubbing with a clean dry cloth. Then, reapply release agent SK2TR450-14 in the same manner as described above.
Mould touch-up:
Since the release film wears during running production, touch-up coatings should be applied frequently. The appropriate frequency of touch-ups required for constant high release performance depends on individual production conditions and has to be determined in on-site trials. We highly recommend to apply the touch-up prior to an observed decrease in release efficiency as this will help maintaining a constant high quality of the moulded parts. We recommend touch-up of the complete mould.
Partial release film repairs:
Occasionally, a partial, drastic decrease in release performance might occur, requiring partial repair of the release film. In this case, remove the worn release film completely 10 cm around the affected area with the help of soft abrasion and wiping with solvent. Note that poor cleanings drastically impair the release film adhesion on the affected areas. Treat the cleaned areas as if they were new (cf. Base coat). Continue by refreshing the film after each demoulding for the first 4-6 releases after the repair. Keep in mind, that the repaired areas are more damageable than others.
